There seem to be a lot of water in the vicinity, what with the water under the stone being ‘seldom dry’, and the same book mentions springs dedicated to St. George and the Blessed Virgin in nearby Reynoldston. This is something about the holy well just to the south of Maen Ceti.
There is also on Cefn y Brynn a remarkable Well, called Holy Well, a very copious Spring, which has the remains of Antiquity about its square Inclosure: Tradition hands down its celebrity for great cures, and it has been customary for the adjacent Neighbourhood to resort to it on Sunday Evenings to drink its water, and pay the tribute of throwing in a pin.
